In Kingdom Protista organisms show both the modes of reproduction that is sexual as well as asexual. Asexual method includes fission, plasmotomy, spore formation and budding.In Binary Fission a parent bacteria undergo mitosis and give rise to two individual cells.n this a small growth occurs on parent body which develops into new individual. Sexual Reproduction started from protists. In this there is formation of gamete. Along with this meiosis occurs which reduces the chromosome number.
Submandibular Lymph Nodes. There are many cervical (neck) lymph nodes, like the Submandibular one, which is in the neck that can cause a swelling or enlargement in the neck. Enlargement can often mean the presence of an infection or disease. Lymphatic fluid drains from different regions of the head and neck.
These lymph nodes are the structures in the upper neck that often become tender during a common sore throat. In fact, many of these lymph nodes are actually located on, within, and deep in the substance of the parotid gland or near the submandibular glands. When these lymph nodes enlarge through infection, you may have a red, painful swelling in the area of the parotid or submandibular glands. Lymph nodes also enlarge due to tumors and inflammation. Tumors: Primary benign and malignant salivary gland tumors usually show up as painless enlargements of these glands.
